context_page_description: The Bofors 57 mm L/70 naval guns are a series of dual-purpose naval guns designed and produced by the Swedish arms manufacturer AB Bofors, designed in 1964 as a revision of the 57 mm lvakan M/50 used on the Halland-class destroyers. Production of the baseline 57 mm Mark 1 variant began in 1966 and was initially used to equip smaller coastal patrol craft and fast attack craft. The gun is remotely controlled by a fire-control computer; as a redundancy measure, however, the crew can also operate the gun using instrument panels that are either on or in direct contact with the gun.
  Although the Swedish Navy is the primary user of the gun, it has been exported widely by Bofors Defence for use by the navies of Brunei, Canada, Croatia, Finland, Indonesia, Ireland, Malaysia, Mexico, Montenegro, Singapore, Thailand and the United States.
  The gun was upgraded and improved several times, first the Mark 2 in 1981 which drastically lowered the weight as well as introduced new servo stabilizers. The Mark 3 came in 1995 with modifications made to enable the smart ammunition developed.
